Definitions

  • the invention relates to a regulating valve for hot water circulation systems, with a valve housing, in which a controlled by the water temperature thermostat element is installed for adjusting a Regulierkolbens, which cooperates with a valve seat with a flow opening between the input and output channel of the valve housing for controlling the Wasser gutflußmenge, and with a device for presetting the regulating piston ( DE 100 56 715 A1 ).
  • a circulation line is laid parallel to the individual risers, the circulation line is connected on the one hand with the riser and the other with the water heater.
  • the hot water temperature in hot water supply networks is preferably in a range of about 50 ° C, which on the one hand for the purposes such as rinsing, washing, showering is completely sufficient and on the other hand, the requirements of the Energy Saving Ordinance takes into account. In addition is at Such flow temperatures in the hot water supply scalding at the outlet fittings unnecessary because temperatures of 50 ° C can not cause damage to the skin of the user.
  • these hot water supply systems are sources of infection for the so-called legionnaire's disease, especially the elderly, preferably smokers and alcoholics as well as people with underlying conditions such as diabetes, carcinomas, leukemia or immune and defensive endangerment, as the pathogens of legionnaire's disease, the Legionella, at temperatures multiply very much under 50 ° C.
  • the thermal killing of bacteria begins at about 60 ° C and the dying time is shortened with increasing temperature very strong. At about 60 ° C this is 30 minutes, while at 70 ° C water temperature, the dying time is only a few seconds. Above 72 ° C, no Legionella could be detected.
  • Propagation and survival of legionella are also favored by stagnation of warm drinking water and the presence of muddy surface coverings (biofilm).
  • This problem has a particularly strong effect on widely branched hot water systems, as they exist, for example, in hotels, hospitals, old people's homes, swimming pools and similar buildings, where there are always hot water pipes or pipe parts that are not used or circulated for an extended period of time and thus standing Contain water at a critical temperature.
  • the warm water of drinking water quality in particularly hazardous hot water circulation networks e.g. in hospitals, nursing homes, etc. maintained above 50 ° C and can be heated in individual cases or periodically to 70 ° C to 75 ° C to perform a thermal disinfection.

  • Such regulating valves are usually installed in each riser return line, just prior to their confluence with the circulation manifold.
  • the regulating valves establish the hydraulic equilibrium of the circulation strands with each other, ie, the pressure surplus of the circulation pump is uniformly reduced by the regulating valves, which perform a throttle function.
  • the regulating valves in the circulating pump close pipe strands set large differential pressures with small volume flows and in the hydraulically unfavorable, pump-distant pipe strands small pressures at high volume flows.
  • the DVGW worksheets W551, W552 and W553 are followed so that all hot water pipes within the system are evenly flowed through high-temperature drinking water of 55 to 60 ° C, so that an increased growth of germs (Legionella) is prevented in the water pipes, and all water pipes of the Network can be thermally disinfected by hot drinking water with a temperature> 70 ° C.
  • the DE 100 56 715 A1 describes a regulating valve of the generic type for hot water circulation systems with a housing having an inlet and an outlet channel and a receptacle into which a valve head is inserted, which is adjustable with respect to a housing-side valve seat and a sleeve-like portion at its the housing side Having valve seat facing end.
  • a sleeve-like closure piece is slidably disposed in the direction of the valve seat, wherein the closure piece is adjustable by a thermostatic element inserted into the valve upper part.
  • the sleeve-like closure member has at its valve seat facing away from and at its end remote flow openings.
  • the stopper has a length such that it is in a first position, which is determined by a predetermined by the thermostatic element distance of the closure member to the valve seat, which is greater than a preset setpoint distance, immersed in the sleeve-like area, in a second position, which is determined by the preset at the valve top setpoint distance of the closure member to the valve seat, both immersed in the sleeve-like portion of the valve top and in the valve seat, and in a third position, by the thermostat element and the constructive fixed exit point of the closure piece from the sleeve-like portion of the valve top is determined, is released from the sleeve-like portion with its rear end.
  • the shutter actuated by the thermostatic element maintains a distance from the valve seat so that water passes through the valve seat the opened valve flows.
  • the closure member is advanced by the thermostatic element so that it dips into the valve seat, wherein between the closure piece and sleeve-like portion of the valve top and also between the closure member and valve seat a defined gap flow with minimal flow exists.
  • the closure member continues to dive further through the valve seat until the rear end of the closure piece slides out of the valve seat facing the mouth of the sleeve-like portion of the valve top.
  • the water flows through the closure piece over the resulting flow cross-section formed between the rear end of the closure piece and the mouth end of the sleeve-like portion of the valve top.
  • This formation of the flow cross-section and the so-called starting point called increase in flow of hot water for the disinfection phase depends only on the stroke of the thermostatic element or acting on this water temperature, that is, the starting temperature, and the constructive fixed exit point of the rear end of the closure member from the valve top from, wherein the closure piece is immersed in the valve seat.
